Various tweaking to get the module formatter to work for 'make docs' in the docs project.  Likely the templates for other module formatting types will have to change
by the time I'm done.

    changed = True when changing symlink referent, #1008. Needed for tests.

As discussed in #923

Make pep8 tests run against the library directory as well, and associated tweaks (mostly to indentation) in the library
directory.

This updates set_owner_if_different() and set_group_if_different()
to not implicitly recurse when setting ownership (whether user or
group).  It drops the os.system() call and replaces it with os.chown().
Resolves issue #825.

The recursion should be explicit.  A recurse=yes|no option should be
added to the file module.

Relative symlinks don't really work (module bug) and would be confusing anyway, better to be explicit.

whitespace + remove deprecated YAML parser (migration script lives in examples/scripts and warning was added
in 0.6 release)

Add encoding lines to python modules such that they can take unicode options if they are fed them, since the
AnsibleModule stuff no longer base64 encodes for simplicity and speed reasons.

secontext is used internally and should not be in argument_spec

Port the file module over to the new common code infrastructure + cleanup some redundant imports since the module code already imports those things.

The ohai and facter modules use /usr/bin/logger to log the fact that
they have been invoked.  I added 'import os' to the ping module
so that it could have the same syslog statements as the other modules.
I separated the condensed:
    shlex.split(open(argfile, 'r').read())
into two separate statements similar to the other modules.

format compatible with this still, and add some tests for INI-style groups of groups
and variables.

This removes the 'context' option and replaces it with checks for
'_default' value for seuser, serole, setype, or (maybe) selevel.
If '_default' is provided *and* there is a default context for the given
file, this will set the file context to the available default.

This adds selinux_mls_enabled() and selinux_enabled() to detect a)
whether selinux is MLS aware (ie supports selevel) and b) whether
selinux is enabled.  If selinux is not enabled, all selinux operations
are punted on -- same as if python's selinux module were not available.
In set_context_if_different(), I now iterate over the current context
instead of the context argument.  Even if the system supports MLS, it
may not return the selevel from selinux.lgetfilecon().  Lastly, this
drops selinux_has_selevel() in lieu of the current approach.

Older versions of selinux, such as that deployed on rhel5, only return a
context of user:role:type instead of user:role:type:level.  This detects
whether the tuple has three elements (old-style) or four.  If the
old-style, it keeps the secontext list at three elements.

This adjusts behavior of file module such that removal of se* option
does not revert the file's selinux context to the default.  In order to
go back to the default context according to the policy, you can use the
context=default option.
